PIN" BETTER AND SPOTTER FOR BOWLING-ALLEYS.

Specification of Letters Patent.

Patented March 2, 1909.

- Application filed June 27, 1908. 'Seiial No. 440,669.

To all whom it may concern:

Be it known that I, JAooB FRED WUERTH, citizen of the United States, residing at Ann Arbor, in the county of Washtenaw and State of Michi an, have invented certain new and useful In rovements in Pin Setters and .S otters for owling-Alleys, of which the f0 owing is a s ecification.

- This invention re atesto pin setters and s otters for bowling alleys, and has for its 0 ject the production of an apparatus havin a perforated platform adapted to be raise and lowered, and having certain features and attachments of special construction and particular arrangement, by which it is elieved the pins maybe more promptly and set upright and spotted. than is ike apparatus accuratel with which I am acquainted.

The stated object is accomplished by fash ioning and associating parts as illustrated in the accompanying drawings, of which-- Figure 1 re resents a front view of all parts assembled. ig. 2 is a front view of one of the pin-raising pro s by itself. Fig. 3 is a top plan view of t e movable perforated platform, and Fig. 4 is a vertical section of the platform upon line x-a: of Fig. 3. I

Like characters are used to refer to the same parts throughout the drawings and specification.

The letter A marks the floor of the alley, and B the ceiling-of the room, above it. At

the sides of the alley are the customary channeled walls 1 and 2, and brackets 3 and 4 are secured to those walls. The brackets support the vertical guide tubes 5 and 6 which have their up er ends fixed to the ovable up and down within the guide tubes are the relatively smaller tubes 7 and 8 which are attached by means of the fittings 9 and 10 to the perforated platform 11. Rising from the platform and curving toward each other are the arms 12, 13 and 14. The platform is normally held in its raised osition b the weights 15 and 16 to which t e'rope 17 is tied at 1ts ends. The rope asses under the pulley 18 which is rotatlvely attached to lock 19, and the rope also passes over the pulleys 20 and 21 secured to the ceiling B at the sides or adjacent to the ends of the guide tubes 5 and 6 already mentioned. It may arms 12, 13 and 14 are attac ed to the block 19 by which connection, therefore, the platform is upheld. The cords 22 and 23, shown in Fig. 1, extend in opposite directions and are tied to the weight rope 17. The cords have a common junction 24 with the draw rope 25.

Considering Figs. 3 and 4 it will be noted that the platform has a number of circular perforations 26 bounded in part by a semic lindrical wall 27. The wall extends both a ove and below the platform, as illustrated in Figs. 1 and 4. Again considering Figs. 3 and 4 it will benoted that one side of each perforation or opening 26 is extended in a recess 28 formed in the upper surface of the platform, and the bottom of the recess is shown to be downwardly inclined toward the openin 26. Flat springs 29 are attached to the walls 27-within the openings 26, and these will be further mentioned.

The pin-raising members, as best shown in Fig. 2, comprise the base block 30, the shank 31, and the rong 32. The shank 31 passes upwardly tl frough the latform and the rong is located in the inclined recess 28.

he base block 30 hangs below the platform, and maintains the shank 31 in a vertical attitude.

The 0 eration of this invention may be thus exp ained-Let it be assumed that the pins have been all overturned and are to be reset. The attendant icks up the pins and places each upon the p atform with its butt toward an opening 26 and its neck restin in the recess 28, as indicated by the bro en lines in Fig. 4. Then he draws upon rope 25, with the result that the weights are raised, the latform descends, and the base blocks 30 of t e in-raising elements come into contact with t e floor of the alley A. The prongs 32 raise the necks of the pins and their bodies sh into the openin s 26 and between the light flat springs 29 wlu'ch serve to accurately center the pins in the o enings and upon their res ective spots. he descent of the weights hf ts the platform from the Ipins. The actual setting and s otting of t therefore, accomplis ed without touching any pin with the hand, and no question of unfairness in positioning the pins can arise.

Havin now described my invention and explaine the mode of its operation, what I claim is 1. In a pin setter and spotter, the combination wit 1 a movable platform having opene pens is, i

ings, of hand-o erated means for raising and lowering the p atform, each of said openin s being provided with a semi-cylindrical wal pin-ralsing members each havin a shank passing movably through the plat orm and 2.

- on one side and a recess on the other side formed in the surface of the platform, pinraising members each having a shank passing Y movably through the platform and a prong 'bination wit upon the upper end of the shank and located in the said recess, and a base block attached to the said shank below the platform, substantially as described.

3. In the in setter and spotter, the coma movable platform having openings, of hand-operated means for raising and lowering the latform, each of said openmgs being rovi ed with a semi-cylindrical wall exten ing above and below the platform, pin-raising members each havin a shank passing movably through the p atform and a prong upon the upper end of the shank and located upon the 0 osite side of the opening from the said wa and a base block attached to the shank below the platform, substantially as described.

4. In a pinwsetter and spotter, the combination with a movable platform having openings, of hand-operated means for raising and lowering the platform, each of said openings being provided with a semi-cylindrical wall, pairs of springs one pair being secured to the wall in each opening and the springs of each pair being secured on opposite sides of the opening whereby a pin may be centered within the opening, pin-raising members each having a shank passing movably through the platform and a prong upon the upper end of the shank and located upon the opposite side of the opening from the said wall, and a base block attached to the shank below the platform, substantially as described.

In testimony whereof I afiix my signature in presence of two witnesses.

JACOB FRED WUERTH.
